Apart from a few popular composers who wrote memorable melodies — Copland, Gershwin, Debussy — the music of the 20th century is still viewed with a surprising amount of skepticism.

In his new book, The Rest Is Noise: Listening to the Twentieth Century, Alex Ross wonders why paintings by modernists such as Jackson Pollock sell for millions while challenging pieces of music, from Stravinsky's Rite of Spring onward, still make many listeners uneasy.

In his book, Ross explores the richness of music in the 20th century, explains how it evolved from the late romantic formulas, and sets the century's great composers within their vibrant, and sometimes violent, social and artistic terrain.

Ross is best known for his insightful music criticism in The New Yorker. He recently spoke with Robert Siegel about his new book, as well as the lingering reputation of 20th-century music as "difficult listening."
